CHECKING FLUID LEVELS

Check transmission fluid with engine and transmission at 158-176°F (70-80°C).
Park vehicle on a level surface and set parking brake.
With engine idling and parking brake engaged, move shift lever from Park to Low and return to Park.
Remove and clean dipstick.
Insert dipstick fully into oil filler tube.
Remove dipstick and verify fluid level is in HOT range on dipstick.
Add fluid as necessary.

RECOMMENDED FLUIDS

For 2003 models, manufacturer recommends Lexus/Toyota Type T-IV ATF. For 2004 models, manufacturer recommends Lexus/Toyota Type ATF/WS ATF.

DRAINING & REFILLING

Add automatic transmission fluid. (Scheme 97)

When adding a maximum amount of fluid (*1): NOTE: Keeping it level. Lift up the vehicle. Remove the refill plug and overflow plug. (Scheme 98) CAUTION: Be sure to add ATF WS. Add ATF to the refill hole until it drains out from the overflow hole. (Scheme 98) Install a gasket and overflow plug. Tighten overflow plug to specification. See «TORQUE SPECIFICATIONS»(ref-156576-S08856031722003072200000). CAUTION: Refill amount is different depending on the related procedures. Refill ATF to the refill hole. See «FLUID CAPACITIES»(ref-156576-S28188566052003072200000). Install a gasket and refill plug. Tighten refill plug to specification. See «TORQUE SPECIFICATIONS»(ref-156576-S08856031722003072200000). Lower down the vehicle. Using an SST, short-circuit between terminals TC and CG of the DLC3. SST (09843-18040). (Scheme 99) NOTE: Turn the A/C off. Start the engine. Slowly move the shift lever from the "P" to the 2-L position. Return the shift lever to the "P" position. NOTE: Standard: Meter indicator lamp "ATF temperature warning lamp" comes on for 2 seconds and then goes off. (Scheme 100) Switch to the fluid temperature detection mode: Move the shift lever from the "N" to the 4D position, or from 4D to "N", within 1.5 seconds. Perform the above procedure for 6 seconds or more. Disconnect terminal TC and CG after confirming the above condition. Idle the engine to raise fluid temperature. NOTE: Add fluid only when the meter indicator light is on. Perform the procedure while the engine is idling. (Scheme 101) Lift up the vehicle right after the meter indicator light "ATF temperature warning lamp" comes on. (Scheme 100) NOTE: Capacity of the overflow tube is approximately 3 cc. Remove the overflow plug.
When fluid overflow (*2): Install a new gasket and overflow plug when the draining ATF becomes a trickle. Tighten overflow plug to specification. See «TORQUE SPECIFICATIONS»(ref-156576-S08856031722003072200000). Install a new "O" ring and refill plug. Tighten refill plug to specification. See «TORQUE SPECIFICATIONS»(ref-156576-S08856031722003072200000). Lower down the vehicle. Turn the ignition switch off.
When fluid does not overflow (*3): Remove the refill plug. (Scheme 98) Add ATF to the refill hole until it drains out from the overflow hole. Install a new gasket and overflow plug when the draining ATF becomes a trickle. Tighten overflow plug to specification. See «TORQUE SPECIFICATIONS»(ref-156576-S08856031722003072200000). Install a new "O" ring and refill plug. Tighten refill plug to specification. See «TORQUE SPECIFICATIONS»(ref-156576-S08856031722003072200000). Lower down the vehicle. Turn the ignition switch off.
When adding a minimum amount of fluid (*4): Using an SST, short-circuit between terminals TC and CG of the DLC3. SST (09843-18040). (Scheme 99) NOTE: Turn the A/C off. Start the engine. Slowly move the shift lever from the "P" to the 2-L position. Return the shift lever to the "P" position. NOTE: Standard: Meter indicator lamp "ATF temperature warning lamp" comes on for 2 seconds and then goes off. (Scheme 100) Switch to the fluid temperature detection mode: (Scheme 100): Move the shift lever from the "N" to the 4D position, or from 4D to "N", within 1.5 seconds. Perform the above procedure for 6 seconds or more. Disconnect terminal TC and CG after confirming the above condition. Idle the engine to increase fluid temperature. NOTE: Add fluid only when the meter indicator light is on. Perform the procedure while the engine is idling. (Scheme 101) Lift up the vehicle right after the meter indicator light "ATF temperature warning lamp" comes on. (Scheme 100) Remove the overflow plug. (Scheme 98)
When fluid overflows (*5): (Scheme 98) Install a new gasket and overflow plug when the draining ATF becomes a trickle. Tighten overflow plug to specification. See «TORQUE SPECIFICATIONS»(ref-156576-S08856031722003072200000). Install a new "O" ring and refill plug. Tighten refill plug to specification. See «TORQUE SPECIFICATIONS»(ref-156576-S08856031722003072200000). Lower down the vehicle. Turn the ignition switch off and remove the SST.
When fluid does not overflow (*6): Remove the refill plug. (Scheme 98) Add ATF to the refill hole until it drains out from the overflow hole. Install a new gasket and overflow plug when the draining ATF becomes a trickle. Tighten overflow plug to specification. See «TORQUE SPECIFICATIONS»(ref-156576-S08856031722003072200000). Install a new gasket and refill plug. Tighten refill plug to specification. See «TORQUE SPECIFICATIONS»(ref-156576-S08856031722003072200000). Lower down the vehicle. Turn the ignition switch off.
